The use of name="cover" in the metadata element name is mandatory.

This syntax is not part of the IDPF standard, because the standard does not provide for cover images.

However, it was designed with help from the IDPF and will validate in an IDPF validator.

3.2.3 Cover Image Guideline #3: Internal Cover Must Not Appear Twice

Do not add cover images to the content in any way other than those described in section 3.2.2, Cover

Image Guideline #2: Internal Content Cover Image Is Mandatory, or the cover might appear twice in the

book.

Amazon strongly recommends the use of an HTML TOC for all books that would benefit from this

navigation feature. This applies to most books, with the exception of fixed-layout children's books (see

section 4) and fixed-layout graphic novels/manga/comics (see section 5).

3.3.1 TOC Guideline #1: Logical TOC Is Recommended

Amazon strongly recommends that all Kindle books include both logical and HTML TOCs. The logical

TOC is very important for a good reading experience, because it allows a reader to navigate between

chapters easily. Users expect to see an HTML TOC when paging through a book from the beginning,

while the logical TOC is an additional way for users to navigate books. The inclusion of a logical TOC is

especially important for books that are longer than 20 pages.

Logical TOCs are generated using toc nav elements or a navigational control file for XML application

(NCX). Creating a logical TOC exposes the hierarchical structure of a Kindle book and allows the user to

navigate through it.

In logical TOC-enabled books, users can see where they are in the book because the part, chapter, or

section is exposed. This progress indicator also shows relative progress through the book.

Important: Nested anchor tags are not supported in fixed-layout books. Fixed-layout books with nested

anchor tags will be suppressed.

3.3.1.1 Creating a Logical TOC Using a toc nav Element

The toc nav element is part of the IDPF 3.0 specification and is described at

http://idpf.org/epub/30/spec/epub30-contentdocs-20111011.html#sec-xhtml-nav-def-model

and

http://idpf.org/epub/30/spec/epub30-contentdocs-20111011.html#sec-xhtml-nav-def-types-toc.

Creating a toc nav element provides both a logical TOC and an HTML TOC.
